I'm a final-year ECE student. Despite coming from ECE, I've always been drawn to backend engineering and solving real-world problems with software. I worked as a Software Engineering Intern at YoForex LLC, where I built an internal workforce operations system adopted across the company by 40+ employees for attendance and activity tracking.

TRACE started as an employee tracking system that I wanted to take much further. I rebuilt and scaled it into a more complete system, reducing p95 latency from 21.4s to 1.49s across 1.1M PostgreSQL rows and bringing screenshot ingestion from 850ms to under 15ms with indexing, Redis, BullMQ, Sharp, and asynchronous uploads.

I also built and launched DSA Quest, a contest tracking platform that has reached 232 active users and 2,000+ page views. I've qualified for Round 2 of TCS CodeVita Season 13 and was 2nd Runner Up at the Hello World Hack Hackathon 2025. I've also solved 600+ competitive programming problems.

I'm mainly interested in backend engineering, scalable systems, real-time applications, and building software that solves problems beyond a demo.
